    Staggering Incompetence

    I've just been in touch with Arnika Apothecary in Germany. They are an often quoted source of methylcobalamin ampules. Before ordering from them, I inquired as to their light exposure precautions during production. This is their response: "We manufacture the methylcobalamin ampoules in our...

    Sterile Methylcobalamin Powder

    Hi everyone, in 2022 Oxford Biosciences switched suppliers of their sterile methylcobalamin powder (used for IM injection). After the switch, their product no longer works for me and feels "dirty" in my system. For nine months now, I've been trying to track down a new source as my health has...

    Questions about Methylation

    I have seen "overmethylation" mentioned in a few threads and I want to ask what is it? How would you know if you were "overmethylating"? I am taking transdermal B12 (methylcobalamin) spray which I bought from Dr Myhill's online shop. She recommends 5-10 sprays daily. I'm currently on 6 sprays...

    Very noticeable improvements in brain fog using Dr Greg Russell-Jones's transdermal B12 oils (which provide a similar dose to B12 injections)

    For the last few months I have been using the methylcobalamin + adenosylcobalamin vitamin B12 transdermal oil developed by Dr Greg Russell-Jones in Australia, which he recommends for ME/CFS. This transdermal B12 oil has made very noticeable improvements in my brain fog and cognitive clarity...
